Peterbilt Oil

I started running this on my 2014 Peterbilt 579 with 880,000 miles. I have used Shell Rotella T6 which is the full full synthetic since I purchased the truck at 300,000 miles. That oil is great, but of course with rising inflation and a slowing economy, it has become somewhat unaffordable. So I switched to this Full Synthetic Sinopec oil. Just an FYI, Sinopec is the Chinese version of the USA MOBILE1. It is a massive global conglomerate. That is why I took a chance on this oil. After 2 oil changes at 20,000 mile intervals, I am satisfied. First and foremost, the process is reminiscent of the Rotella T6 pre-inflation era. My oil burn/consumption has been the same as the T6. I do Texas oilfield work, so this oil gets worked with extreme temps. I highly recommend, especially for Owner Operators.
